made of corrugated board." Corrugatedbard has herel ltofore been`considered unsuitable for wthe outer facesl of fboxes, Iwhich are tohavev a luxury vap'pearancfe which are to` beus'ed for windowdressig,for instance, as inthe case of boxes for relativelyvg expensiveglassware 'to be Adisplayed in shop windows. Thereason isutlrat,4 evenlwhenthe outersurface is-colouredor covered 'withipape-r,

whereby the cost of the box is considerably increased, the corrugationis nevertheless visible at the outer surface as a result of the gluingof fthe interiorly situated corrugated web to the outer sheets of thecorrugated board -at the ridges or crowns of the corrugations. The boxthus has a cheap yappearance and such boxes or other containers havingouter walls constituted by corrugated cardboard are therefore onlyconsidered suitable for inexpensive items or for packages used onlyduring transport from manufacturer to retailer or from store to store.

It is an object of the invention to improve the appearance of boxes,cartons and the like formed of corrugated board without substantiallyincreasing the cost thereof, whereby the eld of application of the cheapcorrugated cardboard boxes and the like is considera-bly expanded toencompass the field for which only more expensive luxury boxes,manufactured from smooth material like sheet board, have been previouslyemployed.

In accordance with an aspect of the invention, the locations of theridges or crowns of the corrugated inner web are masked in a box, cartonor the like having corrugated cardboard Walls by providing at least theouter fiat surfaces of the latter with parallel spaced apart lines,printed or otherwise -applied thereto, and extending longitudinallyalong the ridges or crowns of the underlying corrugated web.

In the case of folding boxes, an attractive effect is further achieved,in that the lines on the folded sides and ends of the box and the coverslidable thereon extend in mutually perpendicular directions, and inthat each of the inner ysides of the box is embellished by the linesappearing on the inwardly folded aps. Notwithstanding the above, thelines need only be applied to one side of the corrugated board.

The means whereby the yabove and further objects to be mentionedhereinafter are obtained will be apparent in the following detaileddescription of an embodiment of the invention which is to be read inconnection with the accompanying drawing wherein:

FIG. l is a perspective view of a folding box with a sliding cover towhich -the invention is applied;

FIGURES 2 and 3 are respectively perspective views of the cover and boxseparately;

FIGURES 4 and 5 are respectively plan views of -at blanks from which thecover and box are formed; and

FIG. 6 is a fragmentary perspective view of a cut piece of corrugatedboard which is provided with lines according to the invention.

The several views of the drawing show parallel lines at equal distancesfrom each other on all outer faces, such as, at 17, 24 (FIG. 1)` and at5, 7, 10 (FIG. 2) of a box and of a cover to be slida-bly placed overthe box, with the box and cover being made of corrugated board.

A

Apart from the fact that the corrugations, which otherwi-se are outlined-against the outer face of the corrugated board giving the latter acheap appearance, have become invisible, so that the outer faces havethe appearance as if they were manufactured from more expensivecardboard, the linear pattern moreover produces an attractive decorativeeffect.

When for instance the linear pattern consists of white lines impressedor printed on coarse, grey or brownish corrugated board, whereby thecost of production remains low, there is nevertheless produced a boxwith a surprisingly attractive appearance, which does not give at allthe impression of a cheap corrugated boa-rd package.

The drawing shows that the invention is in particular `advantageouslyapplied to folding boxes, with only one side of the corrugated boardbeing impressed with the pattern of parallel lines and the latter stillbeing situated on every part of the exterior. In this case, the sidesand ends of the =box and cover have the lines ex- 'tending thereon inmutually perpendicular directions. This results in a further improvementof the appearance.

The folding box with sliding cover which hereinafter will 4be describedin detail presents moreover an embellished interior for the box andcover, even though the linear pattern according to the invention hasonly been applied to one side of the corrugated board.

The blank for the cover (FIG. 4) includes a central plane 5corresponding with the upper side of the cover in FIGURE l and which is`defined in the material by means of creasing (dotted lines) so that itis adjoined on two opposite sides by flaps 6 and 7. The latter are eachin the middle portion thereof provided with a pair of closely spacedcreases 8, 9, respectively. Flaps 10 and 11 are joined to the end edgesor remaining sides of the central plane 5 4and the height a of theseflaps corresponds to the distance Iof the long sides of the centralplane 5 from the crea-ses `8 or 9. The tiaps 10 and 11 are, at theiropposite ends, joined to tabs 12, 13 and 14, 15, respectively, which areseparated lfrom the flaps 6 and 7 by an intersecting line so as to beindependently foldable about the creases shown in dotted lines at theends of the flaps 10 and 11.

In forming the cover of FIGS. 1 and 2 from the blank of FIG. 4, the aps10 and 11 are first erected and the tabs 12 and 13, 14 and 15,respectively, are inwardly folded until they correspond with thelongitudinal bounds of the central plane 5. Thereafter the aps 6 and 7are erected and folded over the tabs 12, 14 and 13, 15 respectively, bymeans of the pairs of creases 8 and 9. The cover is now ready and showson the entire outer side and partially on the inner side a pattern ofparallel lines extending in alternating directions.

The box of FIGS. l and 3 is formed ina corresponding way, with theexception that, as is to be seen in the 3 blank of FIGURE 5, the llaps16 and 17, which are provided with independently foldable tabs 18, 19and 20, 21, respectively are not provided on the short side but on thelong side of the bottom face 22.

As is apparent in FIG. 3, the over-lay flaps 24 and 25 are positioned atthe shorter sides or ends of the box, so that both the inside and theoutside of the box have a variation in the directions of the linearpatterns, as compared with the patterns on the cover.

A further advantage obtained in this way is that everywhere along thesides of the box there is provided four thicknesses of the corrugatedboard when the cover is slidably applied on the box. At the ends of thebox and cover, the four thicknesses are defined by the doubled over aps24 or 25 and the tabs 18 and 19 or 20 and 21, of the box, and by theflap 10 or 11 kof the cover. At the sides of the box and cover, the fourthicknesses of corrugated board are defined Iby the ap 16 or 17 of thebox and by the doubled over flaps 6 or 7 and the tabs 12 and 14` or 13and 15. Thus,'a fragile article in the box is securely protected fromshocks.

What I claim is:

A packing box having walls of corrugated board including outer flatlayers and an interior corrugated layer having parallel ridgesadhesively joined to said flat layers, and printed impressions ofparallel lines at least on the outer surfaces of said walls, saidparallel lines on each wall extending longitudinally in the direction ofsaid ridges of the corrugated layer of the related Wall and beingaligned with said ridges to mask the locations of the yadhesiveattachment of said ridges to the outer flat layer constituting the Outersurface of `said related wall.
